  However, there has been a problem in that manual intervention is involved in the extraction and storage of the station settings constituting the network and the application of the station settings after the setting change to the cellular mobile communication network.

  Also, a method for automatically modeling a cellular mobile communication network from the settings of each station in the cellular mobile communication network when changing the set values of the stations that make up the cellular mobile communication network radio controller for the purpose of expansion and optimization There was no. Therefore, the problem was that human intervention was involved in modeling the cellular mobile communication network.

That is, there was a problem that there was no automation means.

  Accordingly, an object of the present invention is to provide a cellular mobile communication network station setting centralized management modeling system and method for improving the efficiency of setting change of a large-scale network infrastructure.

  In order to solve the above-mentioned problems, the present invention is a cellular mobile communication network station setting centralized management model that is connected to a cellular mobile communication network via a network and centrally manages the extraction and input of each station setting of the cellular mobile communication network.

  FIG. 1 shows a system configuration of the present invention. The cellular mobile communication network station setting centralized management modeling system 3 is connected to the cellular mobile communication network 1 via the management network 2, performs centralized management, and extracts and inputs the setting of each station. The server 4 of the cellular mobile communication network station setting centralized management system controls the extraction and input of each station setting of the cellular mobile communication network 1. Each station setting is stored as data in the storage medium 5 for storage. The extraction and input of the setting of each station can be performed for each station, and can be performed simultaneously for a plurality of stations.

  FIG. 2 shows a cellular mobile communication system station setting change procedure. The cellular mobile communication network station setting centralized management modeling system 3 extracts the setting of each station from the cellular mobile communication network (S1), stores the setting of each station (S2), and structures the setting information of each station of the cellular mobile communication network. Modeling is performed (S3), setting values of each station are changed by network expansion / optimization (S4), and the setting values are input (S5).

  In the cellular mobile communication network station setting centralized management modeling system 3, each station setting stored in the storage medium for storage 5 is automatically extracted by the following method, and is correlated and modeled. . As a result, the station setting data is converted into a cellular mobile communication network radio control unit model that becomes higher-order data.

  In FIG. 3, for each station, the setting for each station is acquired (S11), converted into high-order data of the cellular mobile communication network model, and the cellular mobile communication network model is output according to the following procedure ( S16). This conversion into higher-order data is performed by using a structuring method to convert the cellular mobile communication network into a tree structure model having a hierarchy.

  In the cellular mobile communication network model, each station and cell constituting the network are defined as “nodes”. In addition, this is a model in which the relationship between nodes is “branches”.

  Cell information extraction (S12): Cell information that can be positioned one layer lower than the base station in the configuration of the cellular mobile communication network is extracted from the set values of the respective switching stations. (The switching station of the radio control unit has cell information and base station information corresponding to the lower level as station setting values) By this procedure, each station and cell that is a model node is extracted.

  Layer determination (S13): A layer is determined according to the type of station or cell. The target cellular mobile radio control network model is determined by the type of station or cell. Therefore, if it is determined that the type of station or cell, the layer is determined. The layer order is “cell”, “base station”, “switching station”, and “upper switching station” from the lower layer to the upper layer.

  Inter-layer inclusion relationship determination (S14): After determining the cell layer (S12), it is determined which station of the highest layer is connected. As a result, the inclusion relationship between the layers is determined, and the tree structure of the model is performed.

  Extraction / determination of branch information (S15): By the procedure so far, the connection relationship between each station or cell, which is in the first layer upper and lower layer relationship, becomes clear. Line information of the cellular mobile communication network radio control unit corresponding to the branch portion of the tree structure representing each station or inter-cell connection is also extracted. At this time, it is assumed that the lower layer station side has line information as branch information of a tree structure. Next, branch information of connections between the same layers is extracted.

  By the above procedure, it is automatically converted into a cellular mobile communication network radio control unit model having layers, inter-layer inclusion relations, inter-layer connection relations, and same-layer connection relations.

  FIG. 4 shows a layer structure of a cellular mobile communication network radio control unit model. Through the above procedure, the set value of each station is converted into a model of a cellular mobile communication network radio control unit representing the mutual relationship between the stations (cells). Each station set value data is converted into high-order data modeling the cellular mobile communication network radio control unit. Each station setting of the cellular mobile communication network converted into a model is graphically output and used when changing the setting of each station by expansion and optimization of the cellular mobile communication network.

  As described above, in the present invention, the settings of a plurality of stations constituting the cellular mobile communication network are automatically extracted and stored in one place in the cellular mobile communication network station setting centralized management modeling system. Further, it is characterized in that the stored settings of each station are automatically adapted to the cellular mobile communication network. In FIG. 1, the setting of each station of the cellular mobile communication network 1 is stored in the cellular mobile communication network station setting centralized management modeling system 3 through the management network 2. Conversely, the stored station setting is applied to each station of the cellular mobile communication network 1 through the management network 2.

  In addition, the cellular mobile communication network is modeled by extracting necessary information from each station setting of the stored cellular mobile communication network radio controller and associating them with each other. The setting of each station stored as data in the storage medium 5 of the cellular mobile communication network station setting centralized management modeling system is extracted by the server 4 and is correlated and modeled.
